UP to now, the setting height of the turbine in clear water has been determined by the cavitation number which limits the cavitation conditions.

迄今为止，凡在清水条件下水轮机安装高程都是以限制空蚀条件的空化数来确定的。

Thanks to dramatic advances in wind-turbine technology, the costs of setting up and operating wind generators now approach those of gas turbines, even without subsidies.
